Its low-friction properties enhance dynamic sealing performance while maintaining chemical and\n  temperature resistance. Designed to reinforce primary O-rings, it prevents deformation and extends seal life under\n  fluctuating pressure conditions. Ideal for pumps, valves, and pressure control assemblies, this component contributes\n  to improved system reliability and reduced maintenance requirements.\u003c\/p\u003e\n\n\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n  \u003cli\u003eTeflon back-up ring supports O-rings under pressure\u003c\/li\u003e\n  \u003cli\u003ePrevents seal extrusion in hydraulic systems\u003c\/li\u003e\n  \u003cli\u003eOffers excellent chemical resistance\u003c\/li\u003e\n  \u003cli\u003eLow friction material improves sealing performance\u003c\/li\u003e\n  \u003cli\u003eIdeal for high-pressure applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications\u003c\/h6\u003e\n\u003ctable class=\"TechSpecs__Table-sc-13bifhe-0 fKxfqs\"\u003e\n  \u003ctbody\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eItem ID\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003e17421\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eProduct Type\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003eBack-Up Ring\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eSupplier Name\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003eHaskel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eApplication\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003eSeal protection\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eMaterial\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003ePTFE (Teflon)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003eCompatible Media\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003eHydraulic fluids\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr class=\"TechSpecs__TR-sc-13bifhe-1 jneeGH\"\u003e\n      \u003ctd class=\"TechSpecs__TDshort-sc-13bifhe-3 ldlwAa\"\u003ePressure Rating\u003c\/td\u003e\n      \u003ctd class=\"TechSpecs__TD-sc-13bifhe-2 gNvdTS\"\u003eHigh\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Haskel","offers":[{"title":"Default Title","offer_id":48750746337537,"sku":"17421","price":15.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/4850\/8417\/files\/haskel_157209d1-5bc9-483b-af80-292d63d4c89e.png?v=1778220833","url":"https:\/\/shop.pneumaticandhydraulic.com\/products\/17421","provider":"Pneumatic \u0026 Hydraulic","version":"1.0","type":"link"}
